What risks should I check before replacing CDSOT23-T24CAN?

The main risk is increased junction capacitance, which can degrade high-speed signals like CAN FD. Also verify the peak pulse power and current ratings are equal to or greater than the original part's specifications.

CDSOT23-T24CAN Alternatives, Datasheet & Cross Reference | BOURNS

Finding a replacement for the CDSOT23-T24CAN TVS diode requires matching its 24V bi-directional protection and SOT-23 package. Key alternatives exist but require checking capacitance for CAN bus signal integrity.

AI replacement insight

Electrical riskmedium

Higher capacitance can degrade signal integrity.

Package risklow

SOT-23 is a standard package with compatible footprints.

Can it be replaced directly?

BST23C242V is a very close parametric match, but both it and other alternatives have higher capacitance that must be validated for the application.

Best replacement path

TPNUP2105LT1G offers an upgrade in power rating and is a strong candidate, pending capacitance validation.

Main risk

Increased junction capacitance from alternatives may impact CAN bus signal integrity, especially at higher data rates.

Recommended alternatives

An upgrade with higher power rating in the same package, but higher capacitance requires validation.
